To all whom it may concerm lar at points closely adjacent to the said Beit known that 1, JAMES TOTHAM, of New grooves. The said collar isprovided with a Haven, in the county of New Haven and State set-screw B,located in its plane and enterof Connecticut, have invented anewImproveing its squared central opening A at the 5 5 ment in ReversibleStop and Waste Cocks; corner thereof opposite the groove R aforeand I dohereby declare the following, when said. The said screw is designed tocouple taken in connection with the accompanying the handle C of thecock with the rectangular drawings and the letters of reference markedstem E of the valve E, which, as well as the thereon, to be a full,clear, and exact descripvalve-body F, may be of any ordinary con- 10tion of the same, and which said drawings struction and adapted tooperate on the wellconstitute part of this specification, and rep knownstop-and-waste principle.

Instead of using a lever-handle C, I may employ a T-handle D, having asolid rectangular shank D, constructed with two retaining-notches d andcl.

It is apparent that in carrying out my invention some changes from theconstruction herein shown and described may be made. I would thereforehave it understood that I do not limit myself to the form set forth, buthold myself at liberty to make such changes as fairly fall within thespirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is

In a reversible stop and waste cook, the combination with a body havingtwo stoparms, of a valve located in the said body and constructed with arectangular stein having a hollow rectangular opening, and provided withan outwardly-projecting longitudinal rib located upon the apex of one ofits corners; a stop-collar having a rectangular opening adapting it tofit over the said stem, and formed with two grooves leading out of twoof its adjacent corners, one or the other of the said grooves receivingthe said rib according to the position of the collar upon the stem; ahandle having a rectangular shank adapted to enter the rectangularopening of the said stem; and a screw mounted in the collar andextending laterally through the same and through the valve-stem andimpinging upon the shank of the handle for holding the same, as well asthe collar in place.

In testimony whereof I have signed this specification in the presenceoftwo subscribing witnesses.
